Busan is closer to Fukuoka than it is to Seoul. People forget that, and then they are surprised to learn you can board a ship after lunch and be eating dinner in another country.
One ferry still does it. Just one, and it is not the one most articles describe.
The boat that runs
The New Camellia works the Hakata to Busan route, and the operator publishes its sailing calendar three months at a time. Here is what it says for the current period.
Going Hakata to Busan, check-in opens at 10:30 and closes at 11:30, boarding finishes at 12:10, the ship sails at 12:30, and you walk off in Busan at 18:30. That is a daylight crossing of about six hours, arriving in time for dinner.
Coming back, Busan to Hakata is overnight. Check-in runs 16:30 to 18:30, boarding finishes at 20:00, and the ship leaves at 22:30, docking so you disembark at 07:30 the next morning. You sleep through the sea and arrive with a whole day in front of you.
A detail to get right, because plenty of pages have it wrong: 20:00 is the boarding deadline from Busan, not the departure. Pages that list 20:00 as the sailing time are quoting the wrong row. Turn up to sail at 22:30 and you will watch it leave without you.
It does not sail every day
This is the part that catches people who assume a daily service.
The calendar marks each direction separately, day by day, and they do not always match. On several Sundays the Hakata departure does not run while the Busan one does. Some Saturdays carry an extra overnight sailing from Hakata instead of the usual midday one, boarding finished at 20:00 and sailing at 22:00 to reach Busan at 07:30.
There are one-off variations too. On 7 November 2026 the ship leaves Hakata at 12:30 and arrives at 21:50 rather than 18:30, timed for the Busan fireworks festival.
Check the operator’s calendar against your actual dates. A route with one ship has no second option later that day.
What it costs
The published passenger table runs to 30 September 2026, which is worth noticing if you are reading this later: these are the numbers on the table now, and a new one is due.
Second class is floor space. The berth, 1,500 yen more, is a bed, and on a nine-hour overnight leg that gap is the best value on the sheet.
The fast boat is not coming back
Here is the part worth knowing before you go looking for it, because the internet is full of guides that still recommend it.
For about thirty years a hydrofoil crossed between Busan and Fukuoka in roughly three hours and forty minutes. The last of them was the Queen Beetle, carrying 502 passengers a sailing. In 2024 Japanese authorities found water getting into its hull. The leaks had been recorded since February that year and the sailings had continued anyway.
It was stopped in August 2024. In December 2024 JR Kyushu decided not to resume at all and pulled out of the Japan-Korea fast ferry business, saying the alloy sections letting water in could not be reinforced with confidence, and that budget airlines had made the economics unworkable regardless.
So the three-hour crossing is not suspended, waiting for a refit. It is finished. Plan around a ferry or a flight.
The other boat
If Fukuoka does not suit, Shimonoseki runs a daily service to Busan and has done for decades.
It leaves Shimonoseki at 19:45 and reaches Busan at 08:00. Southbound it leaves Busan at 21:00 and arrives at 07:45. Two ships share the work, the Japanese Hamayuu and the Korean Seonghui, so the one you board depends on the day.
Both directions are overnight, which makes it a night’s accommodation as well as a crossing, and that is how regulars think about the price.
Arriving by sea is still arriving
The ship docks at Busan International Passenger Terminal and you go through immigration like anyone stepping off a plane. Passport, entry check, customs.
Whatever your nationality needs for Korea by air, it needs by sea. The K-ETA rules are the place to check, and the exemption list matters here because Japan is on it, currently through the end of 2026.
Once you are through, the city is right there. Busan’s terminal sits by the old centre rather than out at an airport, and the two-day Busan route works just as well started from a boat as from a train.
The sailing times, check-in windows, the day-by-day calendar and the 7 November fireworks sailing are from Camellia Line’s own published schedule for September to November 2026; the fare table and the compulsory surcharges are from the same operator’s fares page, valid to 30 September 2026 and read on 14 September 2026. The Shimonoseki times and ship names are from Kampu Ferry’s own schedule page. The Queen Beetle account, including the February 2024 leak records, the August 2024 stoppage and JR Kyushu’s December 2024 decision to leave the business, is from Korean press coverage dated 27 December 2024. One ship on a route means one chance a day, so confirm your date against the operator’s calendar rather than against this page.
